Abstract
Determination of natural and man-made radionuclide inventories in water resources is of great importance. Gross α and β measurements are usually carried out as part of such studies. These paper reports measurements performed on water samples from springs in the southwest of caspian region by liquid scintillation method using Wallac-Quantulus 1220 system, 20ml polyethylene vials and Optiphase Hisafe 3 cocktail. With a counting time of 500min, the MDL for gross α and β measurements are 5.36 and 22.26 mBq l-1, respectively. Measurements by EPA 900 technique have also been applied for some samples and the results are compared.
